ZFR1810 Wireless Field Bus Coordinator Installation Instructions8
Note: Only the values associated with the first three
switches (right to left) set to the ON position count
towards the MS/TP address of the ZFR1810
Coordinator. See the top of Figure 6.
Note: On some date code labels, the switch position
numbers on the bottom of the dip switch are reversed.
In either case, the switch positions are always read
right to left.
In Figure 6, the PAN Offset of the ZFR1810
Coordinator is configured by adding the values
associated with the first seven switch positions (right to
left). The eighth switch position is not used. In Figure 6
the PAN Offset is configured to 13 (values 1, 4, and 8)
to the ON position. In Figure 6, the MS/TP address of
the ZFR1810 Coordinator is configured by adding the
values associated with the first three switch positions
(right to left).The sum of the values is 5, so the MS/TP
address of the ZFR1810 Coordinator is 120 + 5, which
equals 125.
Setting the FC Bus End-of-Line (EOL) Switch
The FC Bus End-of-Line termination switch allows you
to designate the ZFR1810 Coordinator as the end of
the FC Bus. The default position is OFF. If the
ZFR1810 Coordinator is at the end of a daisy chain of
devices on the FC Bus, set the EOL switch to the ON
position. See Figure 1 and Figure 7.
Troubleshooting
Wireless Signal Strength
A wireless signal strength indication LED displays the
reception strength of the transmissions between the
ZFR1810 Coordinators, ZFR1811 Routers, and the
WRZ Series Sensors. This LED helps determine the
network connectivity status when selecting locations for
the devices during system installation.
Approximately once every 10 seconds, the Signal
Strength LED flashes to indicate the reception strength
of the signal from neighboring devices. See Table 3
and Figure 1.
Refer to the ZFR1800 Series Wireless Field Bus
System Technical Bulletin (LIT-12011295) for more
information on determining the signal strength between
ZFR1800 Series devices in your application.
WRZ-SST-120 Wireless Sensing System Tool
Use the WRZ-SST-120 Wireless Sensing System Tool
with a WRZ Series Sensor as a site survey tool to
determine the wireless signal strength between a
ZFR1810 Coordinator and a ZFR1811 Router or
between two ZFR1811 Routers. Refer to the
WRZ-SST-120 Wireless Sensing System Tool
Installation Instructions (Part No. 24-10563-12) for
more information on testing signal strength in your
application.
Network Optimize/Reform Button
The Network Optimize/Reform Button allows the
ZFR1810 Coordinator to use any of three functions:
• Signal Strength
• Network Optimize
• Network Reform
Use the Signal Strength mode to aid in signal strength
testing. Signal Strength mode causes the LEDs on the
ZFR1811 routers to turn on and display signal strength
for two hours.
Use the Network Optimize mode to clear the mesh
device routing tables of the ZFR1811 Routers and
attempt to find shorter and/or stronger signal paths to
the ZFR1810 Coordinator.
Note: The Network Optimize process can take up to
15 minutes to complete.
Refer to the ZFR1800 Series Wireless Field Bus
System Technical Bulletin (LIT-12011295) for more
information about the Network Reform function.
